The amount of hit points you get on a level up is random (though weighted in some way, I think), so it wouldn't make sense for there to be a compensation for increased Endurance later in the game. I may well be wrong, but I believe Endurance only affects the upper limit of possible hit point gain. You should have decent Endurance on everyone, and especially the frontliners (Knight and probably Paladin, though that depends on the circumstances). You should aim for a high Int roll on your Sorcerer and to a lesser extent your Archer. Or just go with the pregens, they have good stats. I rolled my own, but if that's not important to you then you could save yourself some tedium.
Pretty sure there's a fountain in first outdoor area outside Sorpigal you can use to jack up your stats before levelling, not really sure how much endurance affects the hp gain though, never really tested it, although i guess it should be pretty easy to by levelling with endurance boost a few times and then levelling with your base stats. In all the M&M games I've played i believe the sp is based off of current personality or int when you rest so shouldn't matter much about having those stats high when you level.
Donating at the temple will give the party a ton of different resistance buffs and other protection spells like Levitate that are really for 1 day. The number of times you have to donate before receiving those spells is random so it can be a whole bunch of times or maybe even once or twice. It was definitely worth it for me when exploring areas like underneath Dusk.
not a mm game
It's alright, but pretty dumb. It's got a great first impression, but once you spend some time with it, it's just boring.
The itemization is a real turnoff. Damned modern RPGs and their MMO influences.
